` CULpTIVATOR.

SPECIFICATION forming part of Lettersy Patent No. 236,243, dated January. 4, 1881,

Application filed June 26, 1880. (No model.)

for work, and the second with the plows raised to avoid obstructions.

In the drawings, 'the letters a, b c represent 15 three plows hinged to an adjustable frame, d, which is provided with boxes e resting on an axle, A, supported by wheels B.

, j' are adjustable segments passing through slots i of blocks g, and adapted to regulate zo thedept-hs of the plows. Thes/egment of the front plow passes through a ,forked lever, h,

connecting with arod, 7 0, provided with bear,

ings on the frame, and having two other levers, h, connecting with blocks g by rods m. 25 By pulling a handle, s, which has the pawl and ratchet 4 4, the blocks are turned back and the plows elevated to avoid obstructions.

The side plows are adjusted as respects their distance apart by shifting the side pieces of the frame on the cross-pieces. 3o

A seat of any suitable kind may be supported on the frame.

I am aware that it is not broadly new to hinge a plow-standard and provide it with an adjustable brace-rod, by which the depth of 35 the plow is regulated.

What I claim as new and of my inntion 1s- 1. The combination, with the hinged plows a b c, ot' the adjustable frame d, the adjustable 4o segments f, the blocks g, having slots t', the forked lever h, the rod lc, having bearingsin the frame, the levers h, connecting, by rods m, with said blocks, and the handle s, having pawl and ratchet, substantially as shown and 45 described.

2. The combination, with a plow-standard hinged to frame d, of the slotted pivoted block g, and the segment f, adjustably connected therewith, as and for the purpose specified.

CHARLES NIEDERAUER.
